AD-TV 22 GVB

Description

The separation amplifier AD-TV 22 GVB serves the galvanic separation and amplification of DC-current signals (0/4-20 mA). The output signal follows linear the input dimension and is independent of the connected burden up to a limiting value. Input, output and supply voltage are galvanically separate from each other with high insulation. An integral electronic power pack with a high degree of effectiveness prevents strong heating and allows high output loads. A high packing density is achieved in combination with a narrow type of construction.

AD-TV 22 GVB

Application

Burden amplification and galvanic decoupling of active DC-current signals in a cost-effective build-up.

Specific characteristics

Supply buffer amplifier for 3-way separation of 0/4-20 mA signals (output follows input 1:1) 13 mm narrow housing
